About rip currents
Duluth New Tribune
Published November 7th, 2004

This summer, the National Oceanic and Atmospheric Administration and the National Weather Service began a media awareness campaign about the dangers of rip currents on the country's coasts and Great Lakes.

Rip currents are the leading safety threat to beach goers, according to the U.S. Lifesaving Association.

A rip current happens when strong wind and high waves perpendicular to shore push water over the sandbar, allowing excess water to collect. The weight of the accumulating water near the shore then "rips" an opening in the sandbar, creating a narrow underwater river that catapults everything in its path out into the lake.

More detailed information on what creates rip currents and how to escape one is available on the Web site for the National Weather Service in Duluth:
